This study aims to examine the application of a modified direct learning strategy combined with the demonstration method to improve students' cognitive abilities. The direct learning strategy is an approach that emphasizes the systematic and gradual delivery of material, so that students can understand concepts in a more structured manner. However, in practice, this strategy needs to be modified to be more engaging and appropriate to the characteristics of students. The demonstration method is used as a form of reinforcement in the learning process, where students not only receive information verbally but also directly observe the processes, events, or concepts being studied. This allows students to gain a more concrete and meaningful learning experience. Modifications to the learning strategy are carried out through adjustments to models, methods, media, and learning facilities and infrastructure to optimally support the achievement of learning objectives. Students' cognitive abilities are the main focus of this study, which include aspects of knowledge, understanding, application, analysis, evaluation, and creation according to Bloom's taxonomy. With the implementation of appropriate learning strategies, students are expected to be able to develop more active and critical thinking skills. The results of the study indicate that a modified direct learning strategy with the demonstration method has the potential to significantly improve students' cognitive abilities. Therefore, this approach can be used as an alternative, effective learning strategy to create a more interactive, engaging, and meaningful learning process.

Sweet corn (Zea mays saccharata Sturt.) is an increasingly popular horticultural commodity in Indonesia, attracting both farmers and consumer. This study aims to evaluate the effectiveness of single‑micronutrient fertilizer Mn‑EDTA (12%) in enhancing the growth and yield of sweet corn (Zea mays saccharata Sturt.). The treatments consisted of control, standard NPK, 0.25 NPK, 0.50 NPK, 0.75 NPK, and 1.00 NPK. The experimental findings demonstrated that the application of single‑micronutrient Mn‑EDTA (12%) fertilizer had a highly significant effect on vegetative growth and yield components of sweet corn, with statistically higher values compared with the control treatment. In general, fertilizer dosages equivalent to 0.25–1.00 NPK produced greater plant height, stem diameter, leaf number, ear length, ear diameter, biomass weight, ear weight with husk, ear weight without husk, plot yield, and productivity than the control. The RAE calculation indicated that the fertilizer was effective when applied at dosages equivalent to 0.75 and 1.00 NPK. The highest effectiveness was observed at the 1.00 NPK dosage, with an RAE value of 101%. Notably, the application of Mn‑EDTA (12%) fertilizer at the 1.00 NPK dosage provided significant field effectiveness, as reflected by the RAE value of 101%. This result implies that the use of single‑micronutrient Mn‑EDTA (12%) fertilizer at the 1.00 NPK dosage increased yield by 1.01 times compared with the yield improvement obtained from the reference fertilizer relative to the control treatment.

The postpartum period is a vulnerable phase often accompanied by lactation problems, particularly ineffective breastfeeding and discomfort due to breast engorgement. These conditions may reduce maternal comfort, inhibit the let-down reflex, and increase the risk of failure in exclusive breastfeeding. Therefore, safe, practical, and comprehensive non-pharmacological nursing interventions are needed. This Final Nursing Project aims to describe the implementation of cabbage leaf compresses combined with breastfeeding education to improve maternal comfort and enhance breast milk flow in postpartum mothers. This study employed a case study method using a nursing care approach involving two postpartum mothers who experienced ineffective breastfeeding and discomfort due to breast engorgement. The interventions were provided for three days and included cabbage leaf compresses and education on breastfeeding techniques. Evaluation focused on breastfeeding ability, pain level, breast condition, maternal comfort, and milk production. The results showed improvement in breastfeeding ability, indicated by the mothers’ ability to correctly demonstrate proper positioning and latch-on techniques. Infants appeared calmer during feeding, and the duration of breastfeeding increased to approximately 10 minutes per breast. Pain scores decreased from 5 to 0–3, breast tension was reduced, and maternal comfort improved. It can be concluded that the application of cabbage leaf compresses combined with breastfeeding education is effective in improving breast milk flow and maternal comfort in postpartum mothers and can be recommended as an independent nursing intervention in maternity practice.

This study aims to determine how Melchizedek's leadership with integrity can be applied by the leaders of the Indonesian Bethel Church in Manokwari. The method used in this research is a qualitative study through reading and reviewing various books and writings. The results indicate that Melchizedek's leadership principles, such as justice, a love of service, and remaining faithful to God, are highly suitable for application in today's church. In conclusion, integrity is crucial in church leadership because it can build trust and create a healthy church community.

The Sehat Indonesiaku (ASIK) Application is a key policy instrument of Indonesia's Ministry of Health designed to improve community health data management, particularly toddler data in Integrated Service Posts (Posyandu). However, implementation at the village level continues to face operational challenges. This study analyzes the implementation of the ASIK program in managing toddler data at Posyandu in Kebonsari Village, Sidoarjo Regency, using George C. Edward III's policy implementation framework. A descriptive qualitative approach was employed, with data collected through in-depth interviews, observation, and documentation from purposively selected informants comprising Posyandu cadres, public health center midwives, and village officials. Data were analyzed using the interactive model of Miles, Huberman, and Saldaña (2014). Findings reveal that ASIK implementation has not been optimal due to constraints across all four Edward III variables: uneven program socialization (communication), limited digital literacy and inadequate device-network infrastructure (resources), dual manual-digital recording workloads (disposition), and over-reliance on core cadres (bureaucratic structure). Nonetheless, adaptive responses including continuous training, structured task delegation, and village government support have been established. This study highlights that the success of ASIK implementation fundamentally depends on human resource readiness, effective policy communication, and institutional support at the local level.

The postpartum period is a critical phase in which mothers experience physiological and psychological recovery. Bengkung, a traditional abdominal binding cloth, is commonly used by Indonesian postpartum mothers, but inappropriate application may cause discomfort and may not support recovery optimally. This community service program aimed to improve postpartum mothers' knowledge and skills regarding safe and appropriate bengkung use. The activity was conducted through counseling, demonstration, guided practice, and evaluation using a one-group pre-test and post-test approach involving 30 postpartum mothers at a community-based maternal health service setting. The educational content covered postpartum physiological changes, indications and contraindications, safe binding principles, hygiene, duration of use, warning signs, and when to seek professional care. The evaluation showed an increase in good knowledge from 26.7% before education to 86.7% after education, and correct practice skills increased from 20.0% to 83.3%. Participants also reported better understanding of avoiding overly tight binding, maintaining breathing comfort, and discontinuing use when pain, shortness of breath, excessive bleeding, or wound problems occur. This activity indicates that structured education and demonstration can strengthen postpartum self-care and support safer integration of traditional practices into maternal health services.

The use of building materials plays a crucial role in determining the quality of the built environment, particularly in the context of row housing in densely populated urban areas. This study aims to evaluate the types of materials used in the construction of row housing in Cemara Asri, Medan, with a focus on sustainability and environmental friendliness criteria. The methods employed include direct site surveys and literature studies related to the characteristics of both interior and exterior materials applied to housing units. The research findings indicate that most of the materials used—such as red bricks, ceramic tiles, clay roof tiles, and concrete ventilation blocks—possess good energy efficiency and durability potential. However, they do not fully meet sustainability standards in terms of production processes and waste management. The study also found that residents' awareness of environmentally friendly material selection remains limited, and the procurement of materials tends to follow local availability and economic considerations. These findings are expected to serve as a foundation for improving environmentally friendly material planning in row housing developments in other urban areas.

This study aims to determine the effect of tax planning and capital structure on firm value, with firm size as a moderator. The population in this study is all non-cyclical consumer companies in the food and beverage subsector listed on the Indonesia Stock Exchange (IDX) for the 2020-2024 period. The type of research used in this study is quantitative associative with secondary data. The research sample was determined using a purposive sampling technique. Based on this technique, 24 companies were obtained that met certain criteria. The panel data regression technique used in this study is the Random Effect Model. Testing of panel data regression and moderation regression uses the E=views 13 application. The results of this study indicate that tax planning partially has no effect on firm value, while capital structure does affect firm value. The results simultaneously show that tax planning and capital structure affect firm value. The results of this study also indicate that firm size weakens the relationship between tax planning and firm value, and firm size is also unable to moderate or weaken the relationship between capital structure and firm value.

This study discusses the analysis of the account opening procedure for E-mas Savings through the digital platform BYOND by Bank Syariah Indonesia. The selection of this topic is motivated by the development of digital services in Islamic banking and the increasing public interest in gold investment products based on sharia principles. The purpose of this study is to identify the procedure for opening an E-mas Savings account and to examine its compliance with sharia accounting principles and DSN-MUI Fatwas. This research was conducted at Bank Syariah Indonesia KCP Tegal Sutoyo using data collection techniques in the form of observation, interviews, and documentation. The study employed a qualitative descriptive approach to obtain an in-depth understanding of the implementation of digital-based E-mas Savings services. The focus of the research was directed toward the stages of the account opening procedure, transaction mechanisms, and the application of sharia principles in digital banking services. The results indicate that the procedure for opening an E-mas Savings account has been implemented in accordance with applicable regulations and sharia principles, although there are still obstacles related to the uneven level of customer understanding regarding digital service mechanisms. In addition, the implementation of digital services through BYOND by BSI is considered capable of providing convenience, efficiency, and flexibility for customers in conducting gold investments without having to visit bank branches directly. Therefore, increased education and socialization for customers are needed so that the utilization of E-mas Savings can run more optimally and enhance public trust in digital-based sharia investment products.

This study aims to analyze the influence of the TikTok application on changes in the lifestyles of teenage girls in the digital age. TikTok, as one of the most popular social media platforms among the younger generation, plays an important role in shaping the way they think, behave, and interact socially. This study uses a qualitative descriptive approach to describe the challenges faced in maintaining a positive lifestyle, as well as efforts to minimize its negative impacts. The results of the study show that TikTok has a dual impact: positively, this platform facilitates self-expression, creativity, and the development of interests; however, negatively, excessive use can trigger consumptive behavior, decreased self-confidence, and deviations from social and cultural values. Factors such as beauty trends, imitation of foreign cultures, and social pressure in the virtual world also influence the lifestyles of adolescent girls. To reduce these negative impacts, it is necessary to improve digital literacy, parental supervision, and education on social media ethics in schools. With a wise approach, TikTok can be used as a positive tool in building the character, creativity, and self-confidence of adolescent girls in the digital age.

The increasing complexity of urban road networks demands intelligent navigation systems capable of determining optimal routes efficiently. This research implements the Dijkstra Shortest Path algorithm to optimize route search on a location navigation system in Medan City. The system models a road network as a weighted graph comprising 57 strategic locations and over 90 road connections, represented using adjacency list data structures. The Dijkstra algorithm, implemented in Python using the heapq module for priority queue management, achieves an optimal time complexity of O((V+E) log V). The system features five main functions: shortest route search, popular routes, location listing, dynamic location addition, and dynamic road connection addition. System testing using a case study from Kualanamu Airport to the University of North Sumatra (USU) yielded an optimal route of 16.5 km through 4 road segments. Results demonstrate that the system successfully determines the most efficient route, provides accurate distance and travel time information for multiple transport modes (motorcycle, car, walking), and presents step-by-step journey guidance. This research contributes as a practical reference for applying shortest path algorithms in urban areas and serves as a foundation for developing more complex navigation applications in the future.

The fish pond farming sector plays a vital role in supporting the local economy; however, fish pond farmers’ incomes remain highly volatile due to fluctuations in production, operational costs, and water quality.

The method used is System Dynamics, involving the creation of a Causal Loop Diagram (CLD) and a Stock and Flow Diagram, simulated using STELLA software. Data were obtained through observation, interviews, and literature review. The results indicate that water quality and fish mortality rates significantly affect production and income. The application of technology helps maintain water quality, thereby stabilizing production. Additionally, the use of alternative energy sources such as solar panels can reduce operational costs. Simulation results indicate that the combination of technology and energy efficiency yields a more optimal increase in profits compared to the initial conditions. This study demonstrates that the application of technology can enhance the income of milkfish pond farmers in a more effective and sustainable manner.

Management psychology is an important approach in managing educational organizations, as it emphasizes understanding individual behavior, motivation, and patterns of interaction within an institution. In practice, educational management requires not only managerial skills but also insight into psychological factors that influence teachers’ performance, the learning process, and overall organizational dynamics. Therefore, studying management psychology is relevant to examine how these concepts are applied in educational settings. This study aims to explore the development of research on management psychology in the field of education and to identify its role and contribution to improving the effectiveness of educational organizations. The research questions addressed in this study are: (1) how has management psychology been developed in educational research, and (2) how does it contribute to enhancing the effectiveness of organizational management in education? This research employs a qualitative literature review method. The literature search was conducted using the Google Scholar database with the assistance of the Publish or Perish application, using the keyword “management psychology.” From the initial 30 articles identified, a screening and selection process was carried out, resulting in 5 articles that were analyzed in depth. The findings reveal three main themes in the literature: classroom and learning management, leadership in educational organizations, and the development of work environment and human resource performance. These results indicate that management psychology plays a significant role in improving the effectiveness of educational institutions. Therefore, future research is recommended to examine the empirical application of management psychology across various educational organizational contexts in order to gain a more comprehensive understanding.

This final project was an audiovisual feature video that explored the issue of uncertainty among informal sector workers, particularly porters at train stations. The work was motivated by the limited representation of porters, despite their important role in supporting transportation services. This report aimed to explain the application of the three-act structure in scriptwriting, consisting of Act I (Set Up), Act II (Confrontation), and Act III (Resolution). The production process included pre-production, production, and post-production stages, with scriptwriting as the main focus in constructing a structured narrative. In Act I, the work introduced the station environment and the porter profession to build audience understanding. Act II developed the conflict through the portrayal of job uncertainty, income instability, and the daily life of the main subject. Act III presented a reflective conclusion through multiple perspectives and symbolic visuals. The result showed that the three-act structure effectively created a systematic narrative flow and strengthened message delivery. In conclusion, the human-interest approach combined with observational visuals effectively conveyed social realities and fostered audience empathy toward informal workers.

Mental health issues among university students have become a growing concern, driven by academic pressures, career uncertainties, and complex social transitions. However, a large proportion of students remains reluctant to seek professional psychological support due to social stigma and limited access to institutional counseling services. This study proposes the design and implementation of an Android-based chatbot application that integrates mood tracking and sentiment analysis to continuously monitor the emotional states of university students. The system employs a fine-tuned RoBERTa (Robustly Optimized BERT Pretraining Approach) model trained on the EmoContext conversational dataset (SemEval-2019 Task 3), comprising 30,160 labeled three-turn dialogue instances across four emotion classes: angry, happy, sad, and others. The model was fine-tuned for four epochs using the AdamW optimizer with a learning rate of 2e-5 and a maximum sequence length of 128 tokens. Evaluation on a held-out validation set of 6,032 samples yielded an overall accuracy of 88.28%, a macro-average F1-score of 0.87, and a weighted-average F1-score of 0.88. Per-class F1-scores were 0.89 (angry), 0.83 (happy), 0.91 (others), and 0.86 (sad). The classified emotion is transmitted in real time to the chatbot response logic, which generates empathetic replies and personalized relaxation recommendations based on the detected mood. Primary data collection through questionnaires and interviews with 62 and 19 university students respectively confirmed the need for accessible digital mental health support. The results demonstrate that RoBERTa-based fine-tuning on conversational data provides a reliable foundation for real-time emotion-aware mental health chatbot systems.

Suspicious urban sound recognition is a critical component of intelligent public safety and urban monitoring systems, enabling the automated identification of anomalous acoustic events such as gunshots, sirens, and other security-sensitive sounds. However, existing deep learning approaches often struggle to simultaneously capture long-range temporal dependencies and global contextual relationships, particularly under noisy and acoustically complex urban conditions. This limitation can reduce reliability in safety-critical scenarios where missed detections carry significant risk. To address these challenges, this study proposes a Multi-Branch Bidirectional Long Short-Term Memory (BiLSTM) framework with Multi-Head Self-Attention (MHSA) for enhanced sequential and contextual feature modeling. Mel-frequency cepstral coefficients (MFCCs) are extracted from a curated subset of the UrbanSound8K dataset, comprising five suspicious sound classes, and used as input to the proposed architecture. The multi-branch design enables complementary temporal representations, while the self-attention mechanism provides lightweight contextual weighting of BiLSTM outputs. Experimental results demonstrate that the proposed model achieves a test accuracy of 95.59%, outperforming conventional Dense and LSTM-based baseline models under identical experimental settings. An ablation study further confirms the contribution of multi-branch integration and attention-based enhancement to overall performance. Class-wise evaluation reveals consistently high recall across all sound categories, particularly for safety-critical classes such as gunshots and sirens. These findings indicate that the proposed framework provides robust and reliable performance, making it suitable for real-time smart city surveillance and public safety applications.

Blasting is a critical method for overburden removal in open-pit coal mines, where fragmentation quality directly impacts loading efficiency and operational costs. This study aims to analyze the actual fragmentation resulting from overburden blasting at Pit 4 Middle of PT. Victor Dua Tiga Mega, Central Kalimantan, to predict fragmentation using the Kuz-Ram model, and to evaluate the conformity of both results against the company standard (boulder size ≤144.6 cm or ≥50 cm for analysis). The research employed a quantitative comparative method. Primary data included blasting geometry and photographs of muck piles from 10 blasting events, which were analyzed using WipFrag software to obtain actual fragmentation distribution. Secondary data comprised rock characteristics and explosive properties for Kuz-Ram prediction input. The results showed significant variation in actual boulder percentage (≥50 cm), ranging from 6.19% to 32.91% with an average of 16.05% (medium category). Statistical analysis revealed a very weak negative correlation (r = -0.21) between powder factor (PF) and boulder percentage, indicating that PF is not the dominant factor within the consistent application range (0.21-0.23 kg/bcm). Comparison with Kuz-Ram predictions showed that the model consistently over-predicted coarse material, with an average difference of +25.21%, suggesting the need for rock factor (A) recalibration. It is concluded that the blasting results are inconsistent, strongly influenced by uncontrollable factors such as geological conditions. Recommendations include geometri evaluation, particularly burden and spacing, and calibration of the Kuz-Ram model for more accurate future predictions.
